Parted with my Johnson 90 after 10 years of faithful service. Any experiences out there with the above Yamaha? I bought one but could find little information other than dealers on the net. So far 50 hours I'm happy. It trolls well, is quiet, pulls a skier and sits on my Lund TYEE 5.3 quite nicely. Only one problem it smokes periodically on startup. Dealer claims this is normal?? Mileage is at least 50% better at 7MPG (measured) than my old motor. Part of the reason for upgrading. I considered only the Honda and Yamaha 4 st but bought Yam as the flywheel and starter arrangement were on top not the bottom and this struck me as easier to repair if needed.
